Research idea: Use airflow analysis (CFD) to test the newtonian theory of lift on an airplane.

Process: First, use CFD data and analysis tools to estimate the mass of air pushed down each second ('m'/dt) by the wings of an airplane in flight; and the vertical velocity ('dv') that this air is accelerated to. From that you can estimate the downward force (Force = ma = m/dt x dv) applied by the wings on the air. The 'equal and opposite' upward force should equal the lift required by the airplane to fly (after deducting induced drag). Then you can test whether the lift generated is adequate to keep the airplane flying.

This idea involves an alternative interpretation of Newtons laws; it is NOT the momentum theory nor the 'flow turning' theory of lift, which are based on Newtons laws (Force = ma = d(mv)/dt).

For more details see the paper: Preprint How the practical aspects of flight affect lift.

Pls keep me informed if you do this research. Thanks.
